{"product_id":"30-in-x-3-7-8-in-metal-door-head-mdh30378","title":"30 in. x 3-7\/8 in. Metal Door Head","description":"\u003cp\u003eThe head is the horizontal top member of a hollow metal door frame, spanning between the two jambs to close out the opening and carry the frame's stop and soffit profile across the top of the door. It is supplied as a separate piece so a frame can be assembled on site, or so a damaged head can be replaced without pulling the whole frame.\u003c\/p\u003e\n\u003cp\u003eLike the jambs it mates with, the head is roll-formed or press-braked from sheet steel into a profile with a stop and returns that wrap the face of the wall on both sides. The throat dimension is matched to the wall thickness it is going into, and the length corresponds to the door opening width. Knock-down heads typically interlock or tab into the jamb tops and are held by the anchors and the finished wall; welded frames have the head joint welded and dressed before finishing.\u003c\/p\u003e\n\u003cp\u003eSteel frame components arrive with a factory prime coat and are meant to be field-painted after installation. Heads should be checked for level and for consistent clearance to the door edge before the wall is closed up, since a racked or crowned head is the usual cause of a door that binds at the top corner.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHorizontal top member of a hollow metal door frame, matched to steel jambs\u003c\/li\u003e\n\u003cli\u003eFormed sheet steel profile with integral door stop and face returns\u003c\/li\u003e\n\u003cli\u003eThroat depth sized to fit standard stud-and-drywall wall construction\u003c\/li\u003e\n\u003cli\u003eSold as a single piece for site assembly of knock-down frames or for replacement\u003c\/li\u003e\n\u003cli\u003eFactory prime finish, ready for field paint after installation\u003c\/li\u003e\n\u003cli\u003eCompatible with standard hollow metal and wood doors of the corresponding opening width\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssembling knock-down steel door frames in drywall partitions\u003c\/li\u003e\n\u003cli\u003eReplacing damaged or corroded frame heads in existing openings\u003c\/li\u003e\n\u003cli\u003eCommercial interior openings in offices, schools and institutional buildings\u003c\/li\u003e\n\u003cli\u003eCorridor, storage and mechanical room doors\u003c\/li\u003e\n\u003cli\u003eBasement, utility and service entries in residential work\u003c\/li\u003e\n\u003cli\u003eTenant fit-out and renovation work where openings are reframed in steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Metal door frame head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Formed sheet steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Component:\u003c\/strong\u003e Head (top horizontal member)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Primed, paintable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As:\u003c\/strong\u003e Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e30\" x 3-7\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55112702591315,"sku":"MDH30378","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/30-in-x-3-7-8-in-metal-door-head-mdh30378.webp?v=1790734576","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/30-in-x-3-7-8-in-metal-door-head-mdh30378","provider":"ARCH","version":"1.0","type":"link"}
